To. all whom 'it 'may concern: l Be. known that l, GEORGE A. Lo'rz, a citizen. of the United States, and resident of Plaineld, in' the' county of Unionand State of New'ale'rsey, have invented certain new and useful Improvements in Elbows for Conduite, of which the following is a speci cation. 4

My vinvention relates to improvements in4 .elbows adapted'for use in connection with electors, vand particularly adapted for makmg connection between such conduits where they extend at an angleto 'each other in the same plane, as at the angle between a wall and ceiling, whereby Tthe open sides of the conduits face each other, suitable means beinguprovided for closing the' open sides of the elbow, all whereby the conductor may be run upwardly along a wall and extended outwardly along the ceiling within the cenduits and elbow.

vThe invention comprises the novel details of improvement that will be more ,fully hereinafter' set forth and then pointed ,out in the claims.

Reference is to be had to the accompanylndrawings forming part hereof, wherein, igure 1 is a perspective view illustrating my improvements in place, Fig. 2 is a side viewv thereof, `Fig. 3 is a central section of Fig.'2, 1`ig. 4 is acrosssection of part of FigQ, taken 011 the line 4, 4, in Fig. 2,-part also being broken away, Fig. 5 is a sectionon the vline 5,5, in-Fig. 4 view of the elbow.` y

Similar numerals of Yreference indicate lcorresponding parts in the, several views.

The numeral 1 indicates, generally, an elbow, shown having two members 'at an anf '1 'gle'to' each other, said members, 'as shown, "extending at right angles to each other` with r`r`their-open slides facingv eachy other v1n the I v4Same 2. The bottom walls 1f plane. The elbow is shown made of sheet metal bent into channelform and adapted to receive or enter the conduit or molding to eachother andthe side walls 1b of each 'member 'of the elbow extend at an angle to each other, and substantially in the same plane,'all whereby the open sides-of ythe channels face each other and 1n the same plane, whereby the elbow may -be ittedm an angle, as between .thewall 3 and ceiling i f4, so that the conduits when Ajoined 'to the-eland Fig. 6 is a rear' extend at an angle Specicationof Letters Patent.

f -bow will extend at an angle to 'each other' in the same plane and have their open sides facing each other in such plane. The elbow may be made of sheet metal stamped toshape, and the blank is shown cut away at a suitable angle, at 5, to permit the members of the elbow to be bent at an angle to each other'. The conduits 2 are shown of the class having Aremovable covers 2? and provided with projecting portionsQb receivingv such covers. r 1

The side walls 1l of the elbow are shown provided with correspondingly shaped or bent port-ions 1 to receive projecting portions otl the conduits when the latter are pushed into the members of the elbow. To accommodate the particular character of* conduit shownthe side wallsv 1b of the elbow are. also provided with bent portions 1l adapted to receive the covers 2 when the latter are pushed into the elbowv members. l

when the projecting port-ions 2b of the condultare inthe bent portions 1c of the A elbowl the bent lor groove-likegportions 1l of the elbow will be in proper 1line to receive the covers 2a of the conduits'.

To -permit the outer portions 1c of the side walls 1b of the velbow to conveniently be made Iwider than the inner lportions l1d the blank may be split yalongV the lines .1g to permit the above describedwidening of the outer :portions-ofthe conduit, and thel bottomv walls 1a ofthe elbow'mayfbe bent outwardly'at 1GL to permit the bottom walls of the conduits toy be depressed "within lthe elbow.l 'loincrease the strength of the elbow -its side walls' adjacenty ythe `dividing line 5l maybe provided with openin s 6 receiving a band or clip `7 bent back t rough the corresponding 'pair "of lholes to aid in holding the members of the elbow together. The endsof the conduits are refera l cured to the members of the e bow, an this purpose I have shown the latter at their se l v. for

back through .slots 2 in the bottom walls of the conduits, although other means may be provided for securing the conduitsto the 1 elbow.

. With an elbow constructed 'in accordance with my invention thesame may be placed in the angle of a wall and ceiling, as shown in Fig. l, land the conduits applied or atbow will closeth'e open sides ofv the latter.

As the inner corner of the elbow is open a conductor may be readily pushed into the same from thefro'nt and does nothave to be pulled around the corner. The 4inner end of one of the covers maybe bent against the endv of the other cover, as at 9- in Fig. 3, forming arounded edge in line witha conductor.

While I have shown a construction of e lbow adapting it to co-act withthe particular form of conduit shown, it will bev understood that changes may be made in the details 'of construction to adapt the elbow to conduits and variations may be made, within thev scope of the appended claims, without departing froml the spirit of my invention..

Having nowdescribed my invention what I claim is: l. An elbow for conduits made .in a piece of 4sheet metal 4bentinto channelform havving open-sided members at a right angle to eachother, thel open` sides of said members facing 'each other said members being permaiiently maintained at a right angle to each othei'.

3. An elbow made in a lsingle piece of sheet metal bent in channelv form having members rigidly maintained at a. right angle to each other and extending in the same plane,'the bottom wall being bent and extending 'at a right angle, with the open sides of said members facing each other and in the same plane and means for 'securing said elbow to the adjacent ends of conduits.

4:. An elbow. in channel form having integral members permanently maintained at .van angle tov each other and extending in 'the same plane, ,with the open sides of said members facing each other and in the same plane, the side walls having.. bent portions7 and conduits having bent wal-ls engaging the bent portions ofthe members.

5. An elbow having open-sided 'men'ibers permanently maintained at a'right angle to 'each other and extending in 'the same plane,
